(N)SSHCGEWÖU Cable 0.6/1kV Heavy-Duty Mining Lighting Cable

(N)SSHCGEWÖU Mine and Tunnel Lighting Cable

(N)SSHCGEWÖU is a 0.6/1 kV monitored cable for lighting circuits in open mines, underground mines and tunnels. Its Class 5 tinned-copper power and control conductors, uninsulated monitoring conductor, semiconductive layers, GM1b bedding, concentric tinned-copper screen and 5GM5 sheath form the non-armoured construction covered on this page. Do not confuse it with the armoured -V variant used for a different machine duty.

• Use when: the lighting circuit requires the documented monitoring function and non-V construction.
• Confirm first: phase, control and monitoring-core arrangement, load, route, termination and protection system.
• Choose another family when: the route is a VFD motor output, high-tensile reel or general heavy-duty power connection.

Compare the complete mining and tunneling cable range and the mobile-equipment selection guide before specifying a replacement for a working lighting and monitoring circuit during operation.

(N)SSHCGEWÖU Cable Construction

Variant boundary: the non-V construction shown here does not include the pliable armour specified on (N)SSHCGEWÖU-V.

Reference construction for coalface lighting to DIN VDE 0250 Part 812

The reference build published for this designation in coalface lighting service is layered as follows, from the conductor outwards.

Read this against the build on this page, do not substitute it. The cable specified on this page carries a concentric overall screen of tinned copper wires. The reference build above specifies the concentric earth conductor as a helix of copper-steel strands. Those are two different constructions. State which one the project requires, with the monitoring system it has to work into, and the matching build will be confirmed against the enquiry.

How the monitoring cores are arranged

The monitoring core is a flexible copper-steel conductor covered with a semi-conducting rubber compound. In the reference build three monitoring cores are twisted together with the working cores and lie in the outer interstices of the laid-up assembly, not in a separate layer. That position is what lets the monitoring circuit register damage arriving from outside the cable before it reaches a working core.

An alternative construction exists for routes where the hazard from impact or crushing is lower. It carries two signalling cores and one monitoring core of tinned copper strands in place of the three copper-steel monitoring cores. The two reference sizes below are these two constructions.

Applications and Selection Boundaries

• Open-mine lighting circuits with an integrated monitoring conductor.
• Underground-mine and tunnel lighting power routes.
• High-output lighting systems exposed to demanding handling conditions.
• Industrial underground utility routes that match the monitored 0.6/1kV construction.

Do not confuse the non-V and -V products

Select (N)SSHCGEWÖU-V when the project calls for the armoured cutter/drill construction. Select an EMC drive cable such as (N)SSHCOEU for frequency-converter motor output. Select (N)TSCGEWÖU for medium-voltage mine distribution.

Why this construction can run without added mechanical protection

The concentric phase monitoring cores and the overall concentric earth conductor work as one circuit. Between them they register insulation faults and the kind of damage that external effects produce, which is why the reference literature states that this cable can be used without additional mechanical protection - no separate armour, no conduit along the route. That only holds while the monitoring system is actually in service and set to trip on the cable's monitoring circuit, so it is a statement about the monitored installation and not about the sheath on its own. Confirm the protection relay and its settings with the enquiry.

Alongside coalface and tunnel lighting, the reference application also covers stationary drives under high mechanical load, in mines above all. A stationary drive on this cable is using it for the same reason a lighting string does: the route is exposed, and the monitoring circuit rather than armour is what guards it.

For the same monitoring philosophy at medium voltage, where the monitoring cores sit under a concentric copper screen instead, see (N)TSCGECWÖU monitored mining cable.

Reference designation cross-reference

The coalface lighting build of this designation is catalogued under its own reference name.

For the full list of reference designations and the TEBAOFLEX build each one maps to, see the mining cable designation cross-reference.

Trademark note: TENAX®, TROMMELFLEX®, FELTOFLEX® and SCHRÄM® are trademarks of their respective owners, and TEBAOFLEX is neither affiliated with those companies nor reselling their cable. What we supply is the equivalent construction: we manufacture to the same VDE type designation and published construction, and every designation listed here can be quoted and supplied as a TEBAOFLEX build. Each TEBAOFLEX build is made to the standards and construction confirmed for the order.

(N)SSHCGEWÖU Specifications

Selection note: verify the phase, control and monitoring-core arrangement, completed diameter, current rating and termination method for the exact size. The monitoring conductor must be integrated with the project's approved protection system.

Reference sizes, the two monitored constructions

In the core notation: KON is the concentric earth conductor, ÜL a monitoring core and St a signalling core. The outer diameter is given as a range because the concentric layer and the cores in the interstices both move it.

The first row is the three-monitoring-core build; the second is the alternative with two signalling cores and one monitoring core. The DC resistance of 3.390 Ω/km is the DIN VDE 0295 / IEC 60228 class 5 limit for tinned 6 mm², so it is a conductor figure rather than a design margin and it does not change between the two rows.

Standards and Order Documentation

The order package should identify core arrangement, monitoring function, dimensions, routine electrical tests, sheath marking, drum schedule and any project-specific inspection requirements. No third-party approval is implied without matching documents.
